The XRAY alu front lower suspension holders provide even greater range of 

adjustment for the front suspension. Using different combinations of eccentric 

bushings, fine adjustment of front kick-up, roll center, and front track-width 

can be obtained. For more information about the influence of  kick-up, front 

track-width, and roll centers on car handling, please refer to HUDY Off-Road 

Set-up Book (#209099).

Eccentric bushings have two different offsets from the center.

  

  Middle position = 0.5 mm or 0.5° from center       

  

  Outer position = 1mm or 1° from center
